No matter what lengths politicians, corporate interests and others take to avoid, downplay and obfuscate serious issues around environmental degradation and our economic system's destructive path, we can't deny reality. Studies show we must refrain from burning most fossil fuel reserves to avoid catastrophic warming. In little more than a century, the human population has more than quadrupled to seven billion and rising, and our plastic-choked, consumer-driven, car-obsessed cultures have led to resource depletion, species extinction, ocean degradation, climate change and more. It's past time to open our eyes and shift to a more sensible approach to living on this small, precious planet.
